17.973 L

16.764 L

18.762 L

23.733 L

After 13 minutes have past, there will be a volume of 18.762 L of punch.

Step-by-step explanation:

In this problem, we are asked to find the volume at 13 minutes. We are given this equation...

y = -2.485x + 51.067

We can use this equation to solve our problem. 13 represents our x-value so, we will plug 13 in for x in the equation above.

y = -2.485(13) + 51.067

Multiply -2.485 by 13.

y = -32.305 + 51.067

Now, add the numbers together.

y = 18.762

So, after 13 minutes have past, then the volume of the punch would be 18.762 L.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
